https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=244048 --- Comment #8 from ml@netfence.it --- (In reply to Konstantin Belousov from comment #7) I doubt it's a hardware trouble: _ this happens on more than one physical machine; _ I too have seen umass troubles (on other machines), but this is usually logged; _ it only happens with 12.1/12.2, not with 11.x; _ umass works perfectly for everything but mksnap_ffs; _ if umass hanged, I don't think this should hang the whole system as only one process is using it; the others are depending on different storage and should not be affected (at least that's my experience); _ the machine I'm debugging is a VirtualBox one (where I was able to recreate the problem): it's not using umass at all. It has system on /dev/ada0 and data on /dev/ada1 (of which I'm taking the snapshot). Underlying hardware is working fine. -- You are receiving this mail because: You are the assignee for the bug.
